Thanks for the good idea! Does anyone have a compiled version for Windows, which I could download somewhere?

Do you have an idea, how we could convert from JPEG2000? It could be also a commercial software (then send me a personal mail to not clog this list).


I would try OpenJPEG first:

   http://www.openjpeg.org/
Something like:
   opj_decompress -i someinputfile.jp2 -o huge.tif
I don't know if it'll write bigtiff. It will write PPM though, which should work.
